SOL Thermal Bivvy - The SOL Thermal bivvy offers more versatility than traditional emergency sleeping bags - the extremely durable fabric resists rips and tears, and thanks to its soft face and aggressive side-venting, it can be pushed into duty as a stand-alone sleep system in warmer weather. Ideal for outdoor users looking for an emergency shelter that can become a regular part of their gear arsenal.

Bigger packed size than the average heat sheet blanket, but this one is very different. Velcro strips on the side allow you to use it as a sleeping bag, or open it up for a tarp. It is also insulated with small air bubbles, kind of like packaging bubbles, but a lot stronger. Worth the extra size and weight if you are going out in cold conditions.
